Question about Panasonic PT-40LC12 40" Rear Projection HDTV

1 Answer

Pt-44lcx65 As I receive the message to clean the fan filter, per your notes I am trying restore the tv so I can watch it without the sutdown message, and to get to the reset function you say to go to the service mode by press the vol- onb the tv and the tv/video remote key at the same time. This seems to work, but I cant get the next step, press the stop/swap part to work. It does nothing and I cant seem to get into anyscreen that has anything to do with the fan filter or reset. Can you please help thanks Marty

How do you reset the bulb life counter after you put in a new bulb?


For models:
PT-44LCX65/PT-52LCX65/PT-61LCX65/PT-52LCX15.
1) Make sure the TV is on.
2) While pressing and holding down VOL DOWN button on the TV, press and hold down the SPLIT DVD/VCR CH UP button on the remote until a message appears on the screen that the lamp timer has been reset. If this does not work, use SPLIT DVD/VCR CH DOWN instead.

Good luck

Howdy,
The problem is with the EEPROM in the TV that needs to be reprogrammed. But you need to have the proper Correction Tool (LSUQ0100).
I don't think it's available to the public. Call a Service Company, but make sure they have the “Correction Tool”.


Thanks for using FIXYA, big IRISH.

How do I clean air filter on the Panasonic PT-50LCX64?


I feel bad for you having such problems with the vendor and the technician too.
The location of that filter could be a small window in the back cover itself. could be a plastic window to the left side of the unit and is only a piece of plastic poliuretane kind of black sponge about 5 by 3 inches size .
What im interested telling you about the shut down condition and is maybe even most important than where is the air filter (who is one of the more than ten posibilities why the tv goes to shut down.
Note:
if the air filter is totally obstructed i would give one of ten probabities of suspicious why the tv shuts down:
first because the tv's air duct is not really isolated. The fan can eat air by any side of the air filter base as i said if the filter is totally obstructing which is really extreme. besides maybe the other 2 fans could help to cool down the unit in that case scenario. In my experience Most time the air filter holds tons of dust but is not totally obstructing the air passing, and really some other problems are in the set.

This is the really critical to know: if any of those fans stopped or maybe any sensor is overheated or the lamp is coming to dead or who knows.. a diagnosis is needed for this symptom really common in DLP technology.

The fix for the air filter problem also you are probably getting the on screen message clogged filter also. It can be repaired by relacing the light engine (VERY EXPENSIVE) or remove the light engine and clean the filter much less cost infact none if you know how.
To clean the filter you must remove light engine and you will see at the top a black housing with two screws that must be removed to remove light engine.
A service maual on how to remove light engine is very helpful wich can be ordered on the internet. Any way you want to remove 4 screws from the housing you will then see the filter and 4 more screws to remove in all four corners, remove the screws and then pry the rectangular filter out of the assembly. This may take some effert so be careful. Look at filter through light it will probably be dirty wash with water and blow it out with comprssed air look at it through to insure it is clean then reinstall .Reassemble and you should be good to go.

Air Filter Cleaning


Call the factory for an authorized servicer near you, your TV guy doesn't understand Panasonic...

If the lamp thermal sensor is active, the fans just keep running because it thinks the thing is hot (to save an expensive part from exploding). It does not give any error message.

Fan 1 is used for air filter detection. (It's essentially the same run-sensor type fan used in their stereos.) Fan 1 plug P2902 at the right side of the light engine board may not be making good contact or the fan is not running. The micro must get the proper feedback signal from that fan to keep it happy.

Good luck, Mark

There is a filter in the front of the machine, right beside the lamp door theres another one. blow that out with can air will kill the error for a while then you might needs to get it serviced because one of the fans is caked with dirt and if you dont know electronics i would not try to take it apart to clean it.
